In the. preferred form, the U-shaped members 32 are supported by wear shoes 37 in the tracks 38 and each member 32 may comprise a number of separate plates carried on a bar 35. The sealing leaves 30 are provided with wearrods 31 making sealing contact with the inner surfaces of the limbs of the members 32, Fig. 3. Although supported by the rotor housing the seals must rotate with the rotor and drive brackets 43 are provided on the rotor for this purpose.

Abstract: 1, 073, 046. Comparing damping factors. TESLA NARODNI PODNIK. June 3, 1965 [July 2, 1964], No. 23707/65. Headings G1N and G1U. An arrangement for comparing damping factors comprises two tuned LC circuits 2, 3 and 2', 3', one being a reference circuit and the other a measuring circuit, two limiting diodes 7, 7' biased from a common stabilized source 8, one connected to each tuned circuit, two means value detectors 4, 4' one connected to each tuned circuit and a measuring instrument 10 connected between the outputs of the detectors. In order to compare the damping factors, or resistances affecting the damping factors of the two tuned circuits, the two circuits are energized from a common impulse generator f imp , the difference in the detected outputs from the circuits being measured on the indicator 10. The arrangement may be used to measure temperature or changes of temperature, by connecting a ferroelectric element across each tuned circuit, each element being heated by the electrical oscillations in the tuned circuits to a temperature autostable state near the Curie temperature. If the ferroelectric elements are placed in enclosures at the unknown temperature and a reference temperature respectively, they will reach autostable states related to these temperatures, and their power dissipation and consequent damping effects on the tuned circuits will depend on these autostable states. By comparing the outputs from the tuned circuits, the temperatures will be compared.

Title: Protection of finished metallic surfaces
Inventor: STEINBERG DAVID J
IPC: B29C63/00
Filed: 1962-06-26
Abstract: 953,777. Laminates and laminating. METAL SKIN CORP. June 26, 1962, No. 24425/62. Drawings to Specification. Heading B5N. [Also in Division B8] Sheet metal is given a protective coating  which will adhere sufficiently to permit handling but is easily removed, by applying to its surface, under pressure, a flexible sheet composed of or impregnated with synthetic resinous material, e.g. polyvinylidene, this sheet being electrostatically charged by friction either before, during, or after application to cause adherence to the metal. If the surface of the metal does not have a mirror finish or if it is coated with a non-metal it is desirable to heat the flexible sheet to a temperature, e.g. between 125‹ and 165‹ F., at which it will become sufficiently softened to conform to the metallic surface irregularities without suffering damage. Preferably the heating is effected by heating the metal sheet at the point of application of the flexible sheet, a radiant gas burner being used. Continuous sheet metal may be carried over a series of rollers (Figs. 2 and 3, not shown) and polyvinylidene sheet fed from a roll supported above the metal and pressed on to it by a pressureloaded roller, typical pressures being 40-80 pounds per square inch. Alternatively a pair of rollers may be carried in a frame (Fig. 3-6, not shown), supported one above the other and in contact so that sheet material can be put through like clothes through a wringer. The roll of plastic sheet is supported above these rollers and contacts the upper one so that when one roller is driven all turn together, thus feeding the plastic sheet on to a metal sheet passed between the rollers and pressing it into contact therewith. The upper roller is of conductive rubber. Nozzles may be provided to spray talc on to the upper surface of the plastic so that it does not adhere to the underside of the metal sheet when the protected sheet is wound into a roll for storage. Examples of pressures and temperatures used with various metal sheets are given. The protective film may be translucent or transparent to permit inspection of the protected surface or it may be of paper impregnated with liquid vinylidene chloride which is then polymerized; indicia may be printed thereon. The sheet metal may, e.g., be aluminium, chrome or nickel-plated steel, stainless steel, brass, or copper and may be coated with epoxy, alkyl or vinyl resins, enamel or other finish.

Title: Correction of distortion in transversal equalisers
IPC: H04L25/03
Filed: 1966-06-02
Abstract: 1,105,959. Transversal equalizers. WESTERN ELECTRIC CO. Inc. 2 June, 1966 [2 June, 1965], No. 24537/66. Heading H4R. The settings of the multipliers in a transversal equalizer are established during normal message transmission using the apparatus of the Figure in which the output from the equalizer, comprising delay line 12, multipliers 15A to 15E and summer 16, is sampled at intervals equal to the reciprocal of the data transmission rate in the sampling gate 17. The resulting samples are fed to one input of a subtractor 32 and to a binary slicer 18 which recovers the binary message stream which is applied to the data utilization device 19 and to the other input of the subtractor 32. The subtractor, being fed with signal samples and with regenerated received binary signals derived from those samples, produces, at its output, an error signal stream which corresponds only to the distortion products, as modified by the existing setting of the equalizer. The error signal is passed through a delay 30, equal to half the total delay of line 12, to one input of each of the multipliers 23A to 23E, to the other input of which is fed the regenerated received binary stream from slicer 18 after feeding through one or more stages of shift register 24A to 24E which has a stepping rate equal to the repetition rate of the received binary stream. The output of the multipliers at any sampling instant is equal to the sum of two terms, one the product of a regenerated digit and the effect of that digit at the particular line tap corresponding to that multiplier, and the other the product of that digit and the effect of other digits through that and other taps. The first of these terms will always be of a sign dependent only on the error of adjustment of the equalizer multiplier on that tap, while the second term will have a sign dependent on the actual digit stream received and will vary randomly. The output of the multipliers is passed through respective low-pass filters 22A to 22E which remove the second term referred to above leaving only a signal which represents the multiplier adjustment required. This signal is gated, via gate 21, at intervals to slicers 20A to 20E to adjust the multipliers, or attenuators, 15A to 15E, in a manner to reduce the distortion products as described in Specification 1,105,958. It is suggested that multilevel data sequence systems may be equalized in a similar way by making slicer 18 multilevel and duplicating shift register 34, multipliers 23, filters 22, gates 21, and slicers 20 for each slicing level.
